RIVETING-MACHINE.

To all whom it may concern:

Be it known that I, CEYLON L. WADE, a citizen of the United States, residing at Detroit, county of -Wayne, Stateof Michigan, have invented a certain new and useful Improvement in Riveting-Machines, and declare thefollowing to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

This invention relates to riveting machines and has for its object a riveting machine which automatically feeds the rivets, makes a hole in the work, and upsets the rivet end.

The machine can be used quite generally in riveting, especially for fiat riveting such as riveting sheet metal plates, riveting on trunks, and riveting in connection with shoes, as for instance fastening the plates or spikes on athletic shoes.

The invention also provides means for holding the work during operation of the tool and stripping the work from tool after line C-C of Fig. 13.

that feeds the rivet movable die which is used to the operation of the holding tool.

Figure 1, is a side elevation .of the machine partly in section. Fig. 2, is a front elevation of the machine. Fig. 3, is a enlarged side elevation of the feeding mechanism. Some of the parts are broken away. Fig. 1, is a section on the line AA of Fig. 3. Fig. 5, is a section on the line B-B of Fig.3. Fig. 6, is a detail of the selector device for feeding rivets one at a time. Fig. 7, is a vertical section of the lower work holder, showing in elevation the dolly-bar to the work. Fig. 8, is a similar fragmentary section showing the dolly-bar raised part way. Fig. 9, is a section similar to the one shown in Fig. 7 showing the dolly-bar completely raised. Fig. 10, is a perspective of the top of thelower work-holder. Fig. 11, is a perspective of a hold the .work while it is being punched or bored. Fig. 12 is a section on the line C-C of Fig. 1, and the Fig. 13, is a view of the traveling head of the machine in side elevation; also the fixed head ofthe machine in side elevation. Some of the parts are broken away for showing. parts to the rear. It is a view similar to that shown in Fig. 1 but on an enlarged scale. Fig.14, is a sectional detail of the lever which governs the Specification of Letters Patent.

operation of the traveling head. Fig. 15, is a sectional detail of the same lever but'having the plane of the section taken a quarter of a turn removed from the plane of the sectionshown in Fig. 14. Fig. 16,-is a vertical section through showing the boring tool is a section showing the machine does. The rivet is a .solid rivet upset to fasten the three flat pieces together.

The machine is shown in its entirety in Fig. 1. Referring tothis figure, aindicates the conventional machine bed which is supported by legs I). A yoke-shaped frame 0 is supported upon the bed. The lower jaw of the yoke is shouldered'as shown in Fig. 7 at d. Into this fits the lower work-holder 6. Again referring to Fig. 1, it will be seen that the upper jaw of the yoke, which will be called the stationary. head of the machine, is provided with the rack 0 In Figs, 12 and 13 this form of construction is shown in detail. This rack is screwed to the dove-tailed tenon f. The dove-tail groove 9 fits about this tenon. The groove and form a track to guide the traveling head upon .the stationary head. The lever h (Figs. 12 and 13) is pivoted to the shaft 11. It carries a spring-pressed dog j which engages with the teeth of the toothed wheel Z. By swinging this lever up and down it is in place. Fig. 17

evidentthat it causes the shaft i to turn be- Consequently the movable head is made to the traveling head,

;tenon kind of work the I rise-or drop with respect to the stationary head. This dog y' is retractable by the reach rodn (Figs. 12 and 13) which connects with (Fig.1) at the end of the lever h.

The shaft 71 (Fig 12) extends through the of the movable head and there terminates with the friction wheel 39. The periphery of with the brakeshoe 9 (Fig. 13 and Fig. 1). This'brake shoe has a stem threaded through the nuts 1' which are on the opposite sides of a laterally protruding bracket. By adjusting these nuts the pressure of the brake shoe upon the friction wheel may be regulated. The bracket and the friction wheel act as a drag so as to hold the lever and the head in any desired position.

The traveling head is provided with a yoke s (Fig. 1 and Fig. 16). -These figures this friction Wheel engages also show the barrel 2? which is provided with a ring at its upper endthat holds it from dropping through the yoke. The barrel is slotted and through these slots protrude the threaded pins u. These pins engage the lower end of the cap a which screws upon the sleeve w. v

The sleeve to is provided with an enlargement at its lower endthat has a dovetailed recess so. Into this recess may be slipped the dove-tailed block y which journals a drill a. This tool is provided with a disk-like enlargement having teeth which can positively interlock with the teeth in the end of the spindle 1. Consequently when the block 1 is in place the drill z is operatively connected with the spindle 1. A portion of thespindle above the cap y is squared (Fig. 16) and this squared portion is slidable through the. gear wheel 2. The spring 98 is a cushioning spring to act when the spindle is used as a pneumatic hammer.

' The gear wheel 2 is a spiral gear which meshes with another spiral gear 3 (Fig. 2).

The gear wheel 3 (Fig. 12) is attached to the shaft 4 which'is journaled in the laterally protruding brackets 5 on the side of the traveling head. The opposite end of the shaft 4 carries a sprocket wheel 6 which engages with the chain 7 at one side (Figs. 12, 2 and 1). Referring to Figs. land 2 it will be seen that the chain passes over two sprocket wheels 8 upon the stationary head.

he upper sprocket wheel is connected by a shaft with the pulley 9 .through the clutch 10. The pulley wheel 9 may be'connected with any convenient source of power. The clutch 10 is linked by suitable connections with the pedal 11. The above mechanism is a flexibledriving connection between the traveling and the stationary head. Consequently'the spindle 1 may be rotated and the drill .2 caused to work when the clutch 10 throws on the power.

Returning to Fig. 16 the coiled expansion spring 12, engaging at its upper end with the pins u on the yoke 8, tends to thrust the barrel a downward and away from the yoke 8 by reason of the lower end of the spring bearing against the inwardly projecting shoulder 13 of the barrel t. -Tl1ebarrel 2? forms the upper work-holder, that, is its lower end bears against the work yieldingly for, when the traveling head is forced downward by the operation of the lever and the interaction of the gear wheel and rack, the yoke s of course goes down with the traveling head until the lower end of the barrel t encounters the, work. The barrel cannot move farther downward and any further .movement of the traveling head is relative with respect to the barrel, because of the yieldin connection between the main part of the iead and the barrel afforded by the coil springl2. Suflicient of this relative movement will bring the drill 2 against the Work and as the drilling progresses further relative movement will allow it to drill through the work. The expansion or split ring 99 frictionally holds the sleeve w in the barrel so that it prevents the sleeve from dropping with respect to the barrel when the drilling tool is lifted out of the work and while the riveting is occurring. The. work is stripped off the drill by lifting the traveling head. This relieves the pressure upon the coil spring 12. The coil spring then expands against the shoulder 13 forcing the end of the barrel against the work while the drill a is lifted out of the work and stripped therefrom. A further movement of the traveling head upward allows the removal of the work if desired. However such removal is not effected during the ordinary operation of the machine but the barrel is left in firm engagement with the work to hold it accurately in place, while the rivet is fedto it and riveted down. The block extends to the outside of the barrel so that it may be Withdrawn by hand while the riveting, is being done (see Fig. l). A slot 15 is provided in the side wall of the barrel.

' Rivets are carried in the receptacle 16 (Figs. 1, 3 and 4). This-receptacle is bolted to the side of the yoke frame and is provided with a sloping bottom, as shown in Fig. 4. A segment 17 is bolted to the arm 18 which is journaled in the boss 19 of the frame. Consequently the segment 17 may be swung y from the position shown in Fig. 3 to, the very bottom of the receptacle. The top of the segment is provided with a groove 20. When this segment is swung to its lowermost'position it is at the extreme bottom of the-receptacle; consequently the whole pile of rivets is over the slot. As the segment is lifted back to position shown in Fig. 3 some of the rivets will tumble into the slot so their stems remain in the slot, while their heads protrude above the slot, as shown in Fig. 3. In the uppermost position the slot of the segment is on the same incline as the raceway 21 which connects with the side of the receptacle. This race-way is formed by a bar provided with a deep slot. The raceway turns a short distance from the receptacle and drops vertically. This requires the use of astrip 22 to prevent the rivets spilling out.

About half way down the vertical run of .the race-way is a pair of holes 23, one on each side and'one below the other. A twopart slide 24 (Fig. 6) is mounted to slide transversely of the race-way by reason of One i away alters the distance and return to select one rivet multiplies the speed and between rest is on one side of the race-way and one on the other and one rest is below the other. The two arms areadjustable toward and from each other vertically by the shown in ,Fig. 6. This betweenthe rests to acsized rivets.

slots and screws commodate difierent Again referrin dent that when t e slide 24 is pulled to the left in this figure the rivet just above the upper rest will drop; before. it can drop below the lower rest that member crosses the groove in the racerway and catches the rivet. When the slide is moved back it is evident that the rivet on the lower rest will be free to drop down the rest will revent' any more rivets dropping onto the ,ower rest or down the race-way. This slide, therefore, operates at each stroke 7 and drop it to, the bottom of the race-way. The slide is operated by a lever 28 that is actuated by a cam, to be hereinafter described.

Referring to Fig. 3, the rivet drops into the tube 29 and in front of the plunger 30.

The plunger 30 has a side extension that protrudes through the side slot 31 in the tube and is fastened as one of thelinks 32 to the chain 33, (Fig. over a large sprocket attached a small gear the toothed segment wheel 34 to which is wheel 35 in mesh with 36. This-transmission peripheral travel consi erably.v Consequently when the foot is removed from the pedal 37 (Fig 1) the coil spring 38 bracket 40 of the bed a to'rise at itsrear end by reason of the connecting link 41..

To this lever 39 is attached a rod 42'prothe, slot 43 in the tail of the segment." This causes the segment to descend and rotates the large sprocket wheel clockwise, causing the plunger 30 to travel forward in the tube 29 car.- rying the rivet ahead of it. The connection the rod 42 and the lever 39 is a lost motion one and the exact point at which the rod is brought into operative relation with the lever can be governed by adjusting the nuts 43 upon the screwthreaded portion. of

the rod. This adjustment is quite essential in order to properly time the plunger 30 so that it travels just the proper distance in performing its work. Referring to Fig. 7, the plunger 30 will be seen at the for ward end of its travel. This is at the mouth of the tube which leads intothe bore of the lower work holder e. When the plunger reaches this last-mentioned position, the rivet will drop through the opening headfirst and will rest upon' the top of the dollybar 44. The end'of this dolly-bar protrudes down through the lower and is engaged by the free end of the lever to Fig. 6, it will be evirace-way while the upper 7). Thischain passes Y pulls the pedal up causing 1 the lever 39 thatis pivoted to the suspended jawof the frame upward. However, by. reason of the lost. motion conneetionbetween the lever 39 and I the rod 32, the plunger .30 tarr'iesat the mouth of-the tube until the rivet passes, so that there is no danger of its being forced out of this opening. As the dolly-bar is forced upward the rivet encounters the die 45 which has acted as a work support while the drilling operation was being performed. Referring to Figs. 10 and 11, the exact form of tube of the holder e and the die 45 will be seen. the slot in the end of the holder by the two springs 46 and 47. The spring 47 is the master spring and of consider-ably more strength than the other spring. The spring 46 operates to hold the die from being forced out by the force of the master spring 47 and also prevents the rivet from being 1 forced out as it-travels upward." Referring to Fig. 8, it will be seen that as the dollybar passes it meets the inclined face 48 of the die 45. This will push the die 45 to the side. The dolly-bar then travels for a little distance over the verticalface 49 of the die. This serves to center the rivet with respect to the hole that has been drilled in the work and consequently guides the rivet into that hole. Further upward progress The die 45 is slidably held in of the dolly-bar results the end of the dolly-bar encounteringthe second inclined face 50 of the die. This contact com letely throws the die to the side, as shown-1n Fig. 9, and the dolly-bar reaches its uppermost osition, the limit of which is marked by the shoulder 51 (Fig. '9) of the dolly-harem countering .the'shoulderb2 of the bore of the lower work holder 6,

I It now remains toupset ,theupper end of the-rivet, for this has nowv passed through the work. This is accomplished vby reciprocatingi the spindle 1 (Fig. 16). It will be'seen that the end of the spindle has a cup recess 53. This comes down upon the end of the rivetand gives it a rounded head. Of course the en changed to form any shaped spindle may be forced up and head. This down by di ferent known means but. most conveniently,

probably,- by an air cylinder and piston. (not shown). The control, however, for such a fluid cylinder and piston is shown in Figs. 14 and 15. By pressing on the push ro 54 in the end of the lever 55 can be forced inward bringing sageway 56 in the valve into registry with the oppositely disposed openings 5 fluid line. This valve may be also worked by the finger58 which protrudes through the top of the lever (Fig. 14). r

Referring to Fig. 5,. it will be seen that the top of the plunger 30 is provided with a cam groove 31;-1nto this protrudes the 7 in the I d of the spindle may be" 1 1207 h, the piston valve the pas- 1 tion of a stationary head, a

a rack on the stationary head, a gear wheel end of the lever 28 which operates the slide. Consequently upon the return of the plunger from the forward end of the tube, the slide, as shown in Fig. 6, is pushed to the right, dropping a rivet before the plunger from off the lower rest. As the plunger starts forward again the lever is again actu-- a-ted and the slide pulled to the left (Fig. 6) dropping a rivet from the upper onto the lower rest which will front of the plunger when it returns again. The slide and the cam which operates the same will be broadly referred toas a selector. d
